Island Pond is the only one where it would prob- 

 ably be possible to capture specimens of this turtle 

 with the seine. I had arranged with Mr. Barbour 

 to seine this pond and obtained the permit for this 

 purpose, but owing to circumstances this was never 

 done. 



Nigger Pond, included in Mr. Babcock's notes, 

 is not on the map, but is a small, privately-owned 

 pond, being under the twenty-acre limit, near the heel 

 of Boot Pond. 



Hallfield or Hillfield Pond is not given on the 

 map, nor included in Davis's list of ponds, nor is it 

 known to myself or to any of my friends. I am in- 

 clined to think the name is an error for "Half-way 

 Pond." If so, this would extend the known range 

 of P. rubriventris in Plymouth by about four miles. 



It may be said that some of the names given on 

 the U. S. G. S. map are not those in use in Plymouth. 

 For example, Ellis Pond above West Pond, should 

 properly be called Sabey Pond. In many instances 

 the apostrophe is omitted, so that we have King 

 Pond, Mica jah Pond, etc., when they should be 

 King's Pond, Mica jah's Pond, etc. 



The weight of ten pounds ascribed to this spe- 

 cies is undoubtedly too great. The actual weight of 

 a specimen of the allied P. mobiUensis, having a cara- 

 pace 13 inches long, is only 6Y2 pounds; so that 5 to 6 

 pounds is probably the weight of a full grown rub- 

 riventris.
